ReceptionRating · Positive reviews · Number of ratings

NetSpot WiFi Analyzer holds the better App Store score, 3.7 against 2.0. That said, the two scores are not equally well evidenced: NetSpot WiFi Analyzer has 337 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of Tether Mobile's written reviews are positive against 18% of NetSpot WiFi Analyzer's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Tether Mobile ships an update every 2 months, NetSpot WiFi Analyzer every 2 weeks. The most recent releases landed on September 10, 2026 and September 30, 2026 respectively.
